Hi caroline and welcome to the forum
Are you saying that a private sector insolvency practitioner has already been appointed?
If you have a complaint against a member of the OR's staff, you should firstly write to the Official Reciever personally, and if the matter needs to cascade upwards then there is an appropriate internal chain of command.
Alternatively you could apply to Court for directions on the issue of the calculation of the IPA if you feel that it is unfair.
Strange that you would sell your house one day before the bankruptcy order and use the money to pay school fees. I assume that your application was a debtor's petition rather than instigated by a creditor. I can understand their concern to be frank, and I suspect that the OR is now in the process of asking the school to return the money. I don't feel that you have a good case here, as you knew that you were insolvent when this asset was sold.
Probably not want you want to hear, but honest!
